"It's tremendously exciting and I would be honoured if she were to wear my designs. I admire her tremendously. She's a beautiful young girl, she has a wonderful figure and I think she wears clothes beautifully," Mrs Beckham said.

Mrs Beckham unveiled her fifth collection at New York Fashion Week in an upper East Side town house that was once a 'Sex & The City' location.

Before introducing each of the 29 pieces for next autumn/winter, as is her signature, she said: "I'm miked-up, but I'm not going to sing, so it's all good."

Wearing a loose beige cashmere "sack" dress with a built-in scarf, she laughed:"This is the only thing in the new collection that fits me. "When I started designing the collection I didn't know I was pregnant."

She denied the various reports which have claimed she is expecting a much-longed-for daughter. "I don't know whether it's a boy or a girl. I knew with the three boys, but this time I wanted it to be a surprise. If it's a boy, the boys will be thrilled to have a little brother and if it's a girl, it will be just as wonderful."

She laughed off reports she intended to "do a Demi Moore" and
pose nude
with her "bump" for American Vogue.

"I'm not posing nude for anybody," she said.

She revealed that husband David was flying into New York tonight "so we can have Valentine's Day together. He's very romantic.

"And he's so supportive. He knows how important this is to me and he's happy to be home taking care of the children."
